1.2 Usage

1.2. 1 When us ing, se lect th e right function and
meas uring r ange.

1.2. 2 Don't e xceed ing ind icated values in each
meas uring r ange.

1.2. 3 When me asuri ng circ uits with the meter
conn ected , do not to uch the p robe tip (metal pa rt).

Warning

Plea se part icula rly note that inap propr iate
use ma y cause s hock or d amage to the meter.
In use , users s hould c omply with commo n
safe ty proc edure s and completely follow t he
safe ty meas ures st ated in the operation man ual.
In ord er to mak e full us e of the meter's
func tions a nd ensu re safe operatio n, plea se
care fully r ead and f ollow the proced ures in t he
oper ation m anual .

1.1. 4 Probe s hould b e in good c ondition. Before use,
plea se chec k wheth er the pr obe insulation is
dama ged, an d wheth er meta l wire is bare.

1.1. 5 Use the p robe ta ble pro vided with the meter to
ensu re safe ty. If neces sary, be replaced with
anot her ide ntica l probe o r one with the same
spec ifica tion.

1.2. 4 When me asuri ng, if th e voltage to be measured is
more t han 60 V DC o r 30 V AC (RMS ), alwa ys keep
your f inger s behin d the fin ger protection device .

1.2. 5 Do not me asure b etwee n measuring end and
grou nd that i s more th an 600 V.

1.2. 6 For man ual mea surin g range, when the value to
be mea sured i s unkno wn in adv ance, choose the
high est mea surin g range f irst and then lower
rang es in seq uence u ntil th e correct range is found.

1.2. 7 Befor e rotat ing sel ector switch to change
meas uring f uncti on, rem ove the probe from the
circ uit to be m easur ed.

1.2. 8 Don't m easur e resis tors, capacitors, dio des and
